10 ways laughter is good for your health

Burns calories

Laughing for 10 to 15 minutes raises energy expenditure, increases heart rate, and can burn up to 40 calories. However, it’s not a weight-loss method. “People can’t eat at McDonald’s and then expect to laugh away their lunch,” says Dr. Maciej Buchowski, a professor of medicine at Vanderbilt University. Even so, a few calories every day translates to a few pounds a year.
